Since the first case of COVID-19 was identified in central China in December, the illness has spread across the world, leading to an outbreak that the World Health Organization has called a pandemic. The maps and charts below show the extent of the spread, and will be updated daily with data gathered from over a dozen sources by the Johns Hopkins University Center for Systems Science and Engineering.

Where COVID-19 has spread in the U.S.

In late March, the U.S. passed China to become the country with the most confirmed cases of the novel coronavirus in the world, and the numbers continue to grow at a rapid rate. As of May 27, the U.S. has over 1.6 million total reported cases and surpassed 100,000 COVID-19-related deaths.

Which U.S. states are flattening the curve?

Here is the rise in the total confirmed cases of COVID-19 per 100,000 residents in each state, plotted by the day that each state reported its first case:

How does the U.S. compare to other countries?

If a community enacts the right protective measures early enough in the process, it can avoid a local outbreak that rapidly spins out of control and turns into a crisis. The goal is to avoid a sharp, concentrated uptick in cases that exceeds the capacity of the health care system, in favor of a lengthier outbreak that stays within the bounds of what the system can handle—resulting in fewer people getting sick and dying overall. This is what experts call “flattening the curve.” The following charts show how 10 nations, including the U.S., have either managed to stem the tide of the novel coronavirus, or are poised for an explosive growth in cases.

Where COVID-19 has spread around the world

Some 180 countries and territories, representing every corner of the globe, have now reported at least one case of the novel coronavirus. In total, there are more than 5.6 million confirmed cases and more than 350,000 related deaths.

Which countries have the most COVID-19 cases?

The U.S. has by far surpassed every other country in the world in total confirmed cases of the novel coronavirus, as well as in total confirmed related deaths.
